Abstract

Disclosed is a heated air popcorn popper which provides a heating base assembly and popping pitcher having an interior popping volume which is detachable from the base assembly for introduction of popcorn kernels. The base assembly providing heated air to the popping pitcher causing unpopped kernels to pop and form popped popcorn. The detachable popping pitcher includes a pitcher lifting handle such that the popping pitcher can be lifted away from the heating base assembly to permit any remaining unpopped or popped kernels to be emptied from the detachable popping pitcher for cleaning.

First claim

The invention claimed is:

1. A popcorn popper, comprising:
a removable popping pitcher comprising: a pitcher body, an upper pitcher opening having a hinged lid member, a pitcher floor comprising an opening, and an interior heating zone located between the pitcher floor and the hinged lid member, the hinged lid member being perforated to allow airflow out of the popping pitcher without disturbing the hinged lid member;
a base assembly comprising: a mounting platform supported by an elevated mounting wall, the base assembly defining an interior mounting area which comprises a fan assembly and a heating member;
the mounting platform comprising an opening and a portion formed to removably engage the popping pitcher such that the opening of the pitcher floor aligns with the opening of the mounting platform to allow heated air to flow from the interior mounting area of the base assembly to the interior heating zone of the popping pitcher;
the upper pitcher opening permitting a popped popcorn kernel to exit the upper pitcher to be collected by a container;
the container formed such that the base assembly forms a lower portion of the container, the container comprising a rear wall, a first side wall, a second side wall, and a top wall which combine with a door assembly to form an interior portion of the container, the interior portion enclosing the popping pitcher.

2. The popcorn popper of claim 1 , wherein the popping pitcher comprises a latch mechanism and the base assembly comprises a latch receiver such that the popping pitcher latchably engages the base assembly when in use, the latch mechanism comprising a positioning tab sized for insertion into a positioning recess located in the rear wall and a latch member sized for engagement with a latch receiver portion of the mounting platform.

3. The popcorn popper of claim 1 , wherein the popping pitcher further comprises a pitcher screen.

4. The popcorn popper of claim 1 , wherein the pitcher screen is located at the opening of the pitcher floor.

5. The popcorn popper of claim 1 , wherein the base assembly further comprises an airflow screen.

6. The popcorn maker of claim 1 , wherein a temperature of the interior heating zone is raised to at least 185 degrees centigrade by heated air passing through the interior heating zone.

7. The popcorn maker of claim 1 , wherein: the popping pitcher comprises a recess formed below the popping floor, and the portion of the mounting platform formed to removably engage the popping pitcher is located at least partially in the recess when the popping pitcher and the base assembly are engaged.

8. The popcorn popper of claim 1 , wherein the popping pitcher comprises a lifting handle, the lifting handle further comprising a latch actuator mechanically coupled to the latch member such that the latch actuator releases the popping pitcher from the mounting platform when actuated.

9. A popcorn popper, comprising:
a removable popping pitcher comprising: a pitcher body, an upper pitcher opening, a pitcher floor comprising a floor opening and a pitcher screen located within the floor opening, an interior heating zone located between the pitcher floor and the upper pitcher opening, a latch mechanism, a lifting handle, the lifting handle further comprising a latch actuator mechanically coupled with the latch mechanism;
a base assembly comprising: a mounting platform supported by an elevated mounting wall, a latch receiver such that the popping pitcher latchably engages the base assembly when in use, the base assembly defining an interior mounting area which comprises a fan assembly and a heating member;
the mounting platform comprising a platform opening, an airflow screen positioned in the platform opening, and a portion formed to removably engage the popping pitcher such that the floor opening aligns with the platform opening to allow heated air to flow from the interior mounting area of the base assembly to the interior heating zone of the popping pitcher; and
the upper pitcher opening permitting a popped popcorn kernel to exit the upper pitcher to be collected by a container, the container not part of the interior heating zone and formed such that the base assembly forms a lower portion of the container, the container comprising a rear wall, a first side wall, a second side wall, and a top wall which combine with a door assembly to form an interior portion of the container, the interior portion enclosing the popping pitcher.

10. The popcorn maker of claim 9 , wherein the popping pitcher comprises a kernel retention mechanism located adjacent to the upper pitcher opening, the kernel retention mechanism comprising a plurality of perforated hinged portions.

11. The popcorn maker of claim 9 , wherein the popping pitcher comprises a recess formed in below the popping floor and the portion of the mounting platform formed to removably engage the popping pitcher is located at least partially in the recess when the popping pitcher and the base assembly are engaged.
